Patent EP-0523151-A1 (EP)
Inventor: LIPSHUTZ BRUCE HOWARD
IPC: C07F1/08
Filed: 1991-04-01
Abstract: On prépare des complexes de cuprates d'ordre supérieur au moyen d'une transmétallisation à partir d'un intermédiaire de zirconate correspondant. Ce procédé est particulièrement avantageux par rapport à la préparation de chaînes latérales vinyliques telles qu'elles sont présentes dans des prostaglandines, puisqu'il est possible selon l'invention d'obtenir directement à partir des précurseurs acétyléniques par l'intermédiaire des cuprates réactifs les produits finaux voulus par une opération à pot unique sans isolement d'intermédiaires et avec des rendements élevés. L'invention concerne également des méthodes alternatives, notamment des additions séquentielles à des intermédiaires de zirconium de composants comprenant ensemble le cuprate mis en oeuvre dans la transmétallisation à l'aide de l'intermédiaire de zirconium.

Abstract: On réalise une fibre céramique en filant une pluralité de matières polymères, dont chacune comprend au moins un précurseur céramique, pour obtenir une fibre composite, après quoi on pyrolyse la fibre composite pour former une fibre céramique composite de composition non homogène. Une matière céramique préférée qui peut être utilisée dans ce procédé est réalisée en pyrolysant un composé organométallique dispersé dans un support polymère organique. Les produits principaux sont des fibres céramiques appropriées, compatibles avec la matrice, qui servent de renforcements et ont une structure de gaine de noyau réalisée par des procédés de filage coaxial. Un noyau ayant les propriétés mécaniques désirées, comme le carbure de silicium, est doté d'une couche superficielle qui convient du point de vue chimique. Des composés de métaux de transition sont préférés, dans une gamme de précurseurs céramiques organométalliques qui comprennent des dérivés de carbone. Les additifs autorisés comprennent les composés métal-silicium, d'autres céramiques, les oxydes métalliques correspondants et des métaux élémentaires.

Abstract: On décrit un système de freinage pouvant être employé aussi bien pour la régulation du glissement au freinage que pour la régulation du glissement à l'entraînement. La régulation du glissement au freinage s'effectue selon le principe du retour, tandis qu'un circuit ouvert est installé pour la régulation du glissement à l'entraînement. Pour pouvoir employer la même pompe (10) dans les deux cas, il est prévu un système de soupapes constitué d'une première soupape de retenue (16) et d'une deuxième soupape de retenue (17) et disposé du côté aspiration de la pompe. La pression d'ouverture de la première soupape de retenue (16) est supérieure à celle de la deuxième soupape de retenue (17). De plus, la pression d 'alimentation du réservoir basse pression (9) est supérieure à la pression d'ouverture de la première soupape de retenue (16). La première soupape de retenue (16) agit pendant un réglage du glissement au freinage et la deuxième soupape de retenue (17) pendant un réglage du glissement à l'entraînement. L'inversion peut s'opérer par exemple par l'intermédiaire d'une conduite de commande (18) sous l'action de la pression dans le maître-cylindre.

Abstract: The uppermost, porous layer (1) comprises a filler-free plastic whose particles have fused together at their points of mutual contact, forming capillaries through which the colouring substance is conveyed in a downward direction. Below this layer (1) is arranged a receiving layer (2) for the respective dye diffusing in through the capillaries. The two layers (1, 2) are on a substrate layer. Since the colouring substance is thus conveyed rapidly through the uppermost layer (1) to the central layer (2) through the capillaries during printing, immediate drying at the surface of the recording medium takes place. Lateral spreading, i.e. blurring of the dye does not take place. No blurred areas are therefore produced and the images are very bright. <IMAGE>

IPC: G01S11/14
Filed: 1992-09-28
Abstract: An apparatus and method are disclosed for detecting the occurrence of transient sonic events, especially for underwater acoustic data. The invention determines an estimate of background environmental acoustic events or noise by computing a short time correlation function for individual segments of data and then subtracting an estimated mean of the correlation function. Acoustical events which represent major excursions from the measured background are detected as transient events. The background is continuously updated within selected processing periods chosen to maintain an accurate differentiation for transient events. In further aspects, the residual correlation function is generally detected using a χ² statistic which is computed using an estimated covariance of the correlation function and the residual correlation function for a specific window. If a given residual does not represent a detected transient event, that residual is used to estimate the mean and covariance of the background using an exponential integrator.

Abstract: An X-ray imaging system includes an vacuum tube, which is biased by a high voltage power supply connected to the tube by two shielded cables. The cables collectively have a plurality of conductors which are coupled at one end to the high voltage power supply. The other end of each conductor is coupled to a component of the vacuum tube by a separate inductor. During a voltage breakdown of the vacuum tube, the inductors depress electrical current flow between the anode and the cathode of the tube to reduce the erosion of tube components which results from the discharge. This current is in part due to the energy stored in the cable, which is not depressed by conventional current limiting circuits in the high voltage power supply. Voltage limiting devices connected to the tube prevent ringing in the cables from generating excessively high voltage levels.

Abstract: A composite, prestressed structural member (10), such as a bridge unit and methods of forming such a member (10). The apparatus includes a plurality of longitudinally extending girders (18) which are transversely spaced and a plurality of adjacent composite units (28) disposed on the girders (18). Each composite unit (28) has a plurality of beams (30) with a molded deck (42) portion formed thereabove. The beams (30) are positioned transversely with respect to the girders (18) and attached thereto. Additional, longitudinal beams (32) are disposed between the transversely extending beams (30) over the girders (18). The longitudinal beams (32) are attached to the girders (18) and by connectors to the molded deck (42). The structure is formed by positioning the girders (18) on a construction support (20) adjacent to a center portion of the girders such that the free ends (22) of the girders (18) cantilever and deflect downwardly. The beams (30,32) of the composite units (28) are attached to the girders (18) in this construction position. Any gaps (48) between adjacent composite units (28) are filled with a non-shrink, high strength grout (60). When moved to an operating position wherein opposite ends (22) of the girders are supported, the natural deflection of the unit due to its weight imparts a compressive prestress longitudinally in the molded deck units (28). Each molded deck unit (28) may be formed such that it is also transversely prestressed.

Abstract: First and second carrier signals, distinguishable by phase, are respectively applied to infrared and red energy emitters (101). A detector (106) receives the sum of the energy after modulation at the infrared and red wavelengths. The signal received by the detector (106) is then demultiplexed into its original first and second components, thereby allowing determining of both the infrared and red modulation components. The first and second carrier signals may comprise time-varying periodic signals with identical frequency and frequency spectra, such as a pair of sine waves which are indistinguishable except by phase and amplitude. A 90° phase difference is preferred, but any phase other than 0 or an integer multiple of 180° is workable. A carrier frequency which avoids excessive interference from ambient light is preferred.
